Microwave power transmission seems like the obvious answer, but is fundamentally flawed due to the thinned-array curse:
> It states that a transmitting antenna which is synthesized from a coherent phased array of smaller antenna apertures that are spaced apart will have a smaller minimum beam spot size, but the amount of power that is beamed into this main lobe is reduced by an exactly proportional amount, so that the total power density in the beam is constant.

- moloch-hai 4y agoPeople promoting space-based solar invariably pick Rube Goldberg complex designs that will reliably fail. A big, very low-mass reflector concentrating sunlight on laser tubes tuned for various wavelengths found in sunlight, and beaming visible light at only solar intensity onto wavelength-matched solar PV farms on the ground, at night, would substitute for storage. Since the light intensity is no more than in sunshine, there is no danger.
